Welcome To Berkeley Math Circle
The Berkeley Math Circle (BMC) is a weekly program for over 400 San Francisco Bay Area elementary, middle and high school students. The weekly sessions are on Tuesdays evenings at the UC Berkeley campus. The program is jointly sponsored by the:
  • UC Berkeley Mathematics Department
  • UC Berkeley Statistics Department
  • UC Berkeley Electrical Engineering and Computer Science (EECS) Department
  • Simons Institute for Theory of Computing
  • Mathematical Science and Research Institute (MSRI)
  • Vanguard Charitable, and
  • Parents' Contribution

Emulating famous Eastern European models, the program aims at drawing kids to mathematics, preparing them for mathematical contests, introducing them to the wonders of beautiful mathematical theories, and encouraging them to undertake future careers linked with mathematics, whether as mathematicians, mathematics educators, economists, or business entrepeneurs.

Berkeley Math Circle for Fall 2014

The Berkeley Math Circle (BMC) for Fall 2014 started on Tuesday, September 2nd.

BMC is divided into two groups: BMC-Upper (grades 5th - 12th) and BMC-Elementary (grades 1st - 4th).

* BMC-Upper:

  • BMC Beginners will meet every Tuesday from 6:15 PM to 7:45 PM at 330 Evans.
  • BMC Intermediate Level I will meet every Tuesday from 6:10 PM to 7:55 PM at 332 Evans.
  • BMC Intermediate Level II will meet every Tuesday from 6:00 PM to 8:00 PM at 740 Evans.
  • BMC Advanced will meet every Tuesday from 6:00 PM to 8:00 PM at 736 Evans.

* N.B.: For questions regarding BMC-Upper, please contact BMC Assistant Hojae Lee at lee.hojae.93 (at) gmail (dot) com


Please check the the BMC-Elementary page for detailed dates on when BMC Elementary I (grades 1 and 2) and BMC Elementary II (grades 3 and 4) meet for Fall 2014.

* N.B.: For questions regarding BMC-Elementary, please contact BMC-Elementary director Laura Givental at bmc.elementary (at) gmail (dot) com

Application for Spring 2015

All levels of the Berkeley Math Circle are currently full for Fall 2014. Those who are interested in joining the Berkeley Math Circle for Spring 2015, there may be a few spots open for each level. The application for Spring 2015 will be available on the week of Thanksgiving and due on the final day of BMC for Fall 2014, which will be on Tuesday, December 16th.


BMC Alumnus Evan Chen is a gold medalist at the International Math Olympiad!

Update: Evan has won a gold medal in the International Mathematical Olympiad (IMO) over this summer. He represented the Taiwanese team (which came in 3rd), but Evan actually came in second at the USAMO earlier this year, the final round of the USA Olympiad. Evan is now starting his freshmen year at Harvard College, and will be in contact with the BMC through his Monthly Contest problems. Congratulations and good luck in college, Evan!

Berkeley Math Circle student Evan Chen, also the coordinator for the Monthly Contest at BMC for the past three years, solved all six problems at USAMO (the last round of the USA Math Olympiad). He was placed #2 in the USA with 41 points and was among the top 3 winners awarded with Akami Foundation Scholarship! Even more astonishingly, he qualified at the same time on the Taiwanese team and participated in the International Mathematical Olympiad this summer in Cape Town, South Africa, from July 3-13 , 2014.

Evan Chen graduated from lrvington High School in Fremont, CA, this year and will attend Harvard College in the fall. Evan earned a Gold medal in the 2013 Asian-Pacific Math Olympiad, and will be participating on the Taiwan team at the 2014 lnternational Mathematical Olympiad (lMO). He enjoys programming, typesetting documents in LaTeX, and playing StarCraft on the nights before major contests. Evan applies his skill as a competitor in mathematical competitions to writing mathematical problems. Evan thanks his teachers, Miss Chiu and Mrs. Rothfuss, for their continual support and Dr. Zvezda Stankova, of the Berkeley Math Circle, for her invaluable mentorship. lt is noteworthy that Evan took this USA Mathematical Olympiad (USAMO) in Taiwan from 12:30 a.m. to 5:00 a.m. while in Taiwan.

Espen writes a poem!

BMC student Espen has written a beautiful poem called "My True Number". We wanted to share as it is quite appropriate for the Berkeley Math Circle! Please do not take out the poem without copyright.

My True Number
By Espen Slettnes, Jan 6th, 2014

My shadow and I stood in a complex plane.
"What value are you?" I winked and asked.
"3435i", said he, and he asked me mine.
I said I was 33+44+33+55.
"That's what I am, but times i"he replied.
Our eyes met and danced
as we added and multiplied and exponentiated and tertiated
until we reached the magnitude of beauty,
in the silence of ∞, where I saw my true self.
I spoke no words but the simple language of the universe.
I rose and vaporized into numbers,
integrated with the Universe,
and we became 1.


  • The complex plane is a way to represent all complex numbers in 2 dimensions. A complex number is made up of a real and imaginary part.
  • i is the imaginary unit, defined as √ -1 
  • Tertiation is repeated exponentiation, which is repeated multiplication, which is repeated addition.
  • ∞ means infinity - larger than any number
  • (33+44+33+55) = 3435 (each digit raised to its own power)

Nico Brown of the Berkeley Math Circle wins first place at the Berkeley Mini-Math Tournament!

Nico Brown wins 1st place at BmMT 2013.         Nico Brown and Vincent Pisani at BmMT 2013.

BMC's own Nico Brown won the Berkeley mini Math Tournament (BmMT), the middle school student variant to the BMT for high school students, this past weekend.

Nico's score in the Individual round placed him into the top six students who entered the final Countdown elimination round, a series of timed questions... and he emerged the overall champion!

He wouldn't have got there without Team BMC coached by Intermediate Circle parent Tor Slettnes--Vincent Pisani, Arav Karighattam, Nate Fish, Espen Slettnes, and Nico--so congratulations to all!

Laura Pierson of the Berkeley Math Circle wins Silver Medal at 2013 European Girls' Mathematical Olympiad!

Current BMC Student Laura Pierson won a silver medal at the European Girls' Mathematical Olympiad (EGMO)! The 2013 EGMO was held at Luxembourg city, where 87 participants from 22 countries participated. As a 7th grader at the time, Laura was the youngest member of the USA team.

Congratulations, Laura!

BMC Student Evan Chen wins Gold Medal in the Asian Pacific Mathematical Olympiad 2013!

BMC Student Evan Chen participated at the Asian Pacific Mathematical Olympiad 2013 as part of the Team Selection Tests. USA, Korea, and Russia tied for the 1st place. Evan Chen was placed as USA #1 and received the gold medal. In fact, all USA members received perfect scores, however, Evan Chen won the tie-breaker!

Congratulations Evan!
